DIE FOR MAKING ADZES.

SPECIFICATION forming part of Letters Patent No. 258,570, dated May 30,1882.

Application filed June 15, 1881. (No model.)

To all whom it may concern Be it known that I, WILLIAM EVANS, a citizenof the United States of America, residing at Chester, in the county ofDelaware and State of Pennsylvania, have invented certain new and usefulImprovements in Dies for Manufacturing Adzes and Similar Articles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form part of this specification. I

This invention relates to the manufacture of adzes and similar articlesby machinery.

My invention consists in the novel construction of the dies formanufacturing adzes, as will be hereinafter described, and pointed outin the claims.

Figure 1 of the drawings is a representation of the metal blank. Fig. 2is a view of the bottom die for forming the depressed portion to shapethe eye. Fig. 3 is a perspective view of the top die. Fig. 4 is aperspective view of a fullering-die. Fig. 5 is a sectional view of thefullering-die, taken through the line w x of Fig. 4. Fig. 6 is a sideview of the blank after being operated upon by the fullering-die. Fig. 7is a plan view of the punch-dies. Fig. 8 is a view of the punch. Fig. 9is a view of a pair of dies for shaping the poll, socket, and bit. Fig.10 is a view of the final dies for shaping the adz, and Fig. 11 is aperspective view of the adz.

The method or process of manufacture is as follows I take from abar ofiron of the proper size a piece about the weight of the adz I wish tomake, which I call the blank or stock A, as shown in Fig. 1 of thedrawings. This blank is heated to a white heat and placed in the die B,which is constructed with a. transverse recess, a, and a flange, b, andsubjected to a blow or blows by the flatface die 0 to break down thestock near one end to form the socket-piece d, as seen in Fig. 2. Theblank is next turned sidewise and placed in the second die, D, one of apair for fullering the metal at the eye or socket portion. Each of thesesectional dies D is formed with a longitudinal passage, 6, for the bodyof the blank and the groove or passage f, arranged at right anglesthereto, (see Fig. 4,) the bottom of which is curved for the purpose offullering the eye or socket portion of the metal. The advantage offullering is to spread the metal for forming the socket or eyeextensions of the adz and compress the metal around the eye to securestrength. The appearance of the blank after leaving thesediesisrepresentedbyFig.6. Thisshapedblank is now placed in a third die,E, with a cavity (see Fig. 7) having the outlines to receive the same,and while the blank is arranged in this die a hole is formed in thesocket portion by meansofapunch,E,(seeFig.8,)withoutremoving any metal.The blank is next placed in between the fourth pair of dies, FF, (see Fi9,) the lower one of which is formed with asquare opening and ashoulder, h, and the cavities i 70 for the head and blade portion of theadz, and the upper one with punch m for shaping the socket or eye. Theadjacent or meeting faces of the dies are curved, as shown, to give thedesired curve to the back of the adz. The metal at the blade end isagain (the second time) heated to a welding heat and split to receive asteel bit, likewise heated to a welding heat and placed between thefifth or finishing pair of dies, H H, the lower one, H, of which isfor-med with a poll or head cavity and a depression of the shape of theblade to be struck up, and the upper one witha steady eye-pin, n. Theadz as it comes from this pair of dies is represented by Fig. 11, andnow only requires to be tempered and polished for the market. 7

It is obvious that the progressive steps in the method of manufacturingherein set forth will apply to the forming of adzes from a steel blank,in which case the splitting and welding are omitted.

Heretofore in the manufacture of adzes eight heats of the metal wererequired; but by my improved method or process onlytwo heats arerequired to manufacture the adz.

This method of manufacturing adzes by the series of dies arrangedin apress in progressive steps improves the quality of the article andreduces the cost of manufacture.

What I claim as new, and desire to secure by Letters Patent, is-

1. Jointly, the die B, formed with the trans verse groove a and flangeb, and die 0, with a plain surface for breaking down the metal,substantially as described.

2. Jointly, the dies D, each constructed with the longitudinal groove 0and the transverse convex surfaeefisaid groove and surface beingarranged as shown, for the purpose of fullering the metal.

3. The die E, substantially of the construction seen in Fig. 7, for thepurpose stated.

4. The pair of dies F Fthe former or lower one formed with squareopening, shoulder h, and cavities i It, and the latter or upper oneprovided with a punch, m, substantially as and for the purpose setforth.

5 5. The pair of dies H H, substantially of for manufacturing adzes inprogressive steps. 20

In testimony whereof I affix my signature in presence of two witnesses.
